Its scope is specified as gas, liquefied gas, steam medium with a maximum working pressure greater than or equal to 0.1MPa (gauge pressure), or flammable, explosive, toxic, corrosive liquid medium, or liquid medium with a maximum working temperature greater than or equal to the standard boiling point, and the nominal diameter is greater than 25mm. These pipes play a vital role in the boiler system, responsible for safely and efficiently transporting various media to each required location. After the production of the boiler pressure piping is completed and before installation and laying, the pipeline surface needs to be inspected. One of the inspection items is ultrasonic testing. Ultrasonic testing can quickly, conveniently, non-destructively and accurately detect various defects inside the workpiece, such as cracks, welds, pores, sand holes, inclusions, folds, etc., which requires the use of ultrasonic testing equipment.

In addition, some pressure pipes are curved, making ultrasonic inspection even more difficult. In short, the inspection process is time-consuming and labor-intensive, with a large workload, and low ultrasonic inspection efficiency.
